Rebel XT 350D - Lockups, freezes, crashes

[gui_maranhao]

Hello everybody,

 

I have had this problem occur for the second time now, the camera (with no

particular lens attached, no particular card in it, no external flash on camera

or PC adapter) simply stops responding to any input. After removing and

reinstalling batteries it comes back to life.

 

I googled the thing, there was one hit here in photo.net, and another similar

one at another forum. Both cases ended up with camera sent back to Canon because

it was still in warranty, but no one found a root cause. Mine is not under warranty.

Some peole report things similar with the 20D.

 

One post referred to the flexing of the plastic body as the possible cause, the

person reported he would push the body with his finger, above the control wheel

on the back making the problem appear. I tried all sorts of things like that, no

show.

 

I checked my firmware, I have 1.0.3 (latest) pre-installed, so there's no

firmware to go to.

 

The grip was attached to the camera both times it happened. No one metioned the

grip in other posts. The first it happened, I removed both the batteries and the

grip, just to make sure because it showed an empty battery signal on the LCD (I

cleaned the contacts between grip and battery and between grip and camera). The

second time, simply removing the batteries did it, the camera didn't show

anything different, simply froze at the metering stage.

 

I'm not an eletronics expert, but could the grip and its circuitry to switch

power from each battery be the cause?

 

Since 2005, has anyone else had this problem? How did you fix it?

 

Regards,

Guilherme

Sometimes the battery contacts get bent a bit and that could cause problems like this

perhaps. You might take a look at that and perhaps try to slightly bend them back into

position if that seems possible for you - or send it to Canon...

 

Sounds like the issue could be in the grip, right?

Digital cameras are computers with optics. If your computer locked up twice in the last couple years, and your were forced to reboot it both times, would you send it in for repair? Now if it's doing it twice a day you should be annoyed, but as it stands, it sounds like you have a nice camera with an infrequent glitch.

I recharged the battery and reformatted the card. No problems since!

The fix is easy - you just send it to Canon for repair :(

I've had the same problem. Twice. The first time was in very bad weather - 8000feet, rainy, extremely humid. The second was on a sports event after 2000+ frames constant shooting. I don't think it's abnormal. Like Jim Strutz said: this is a computer with lens. If it crashes 2 times a week it's not OK, but 2 times a year is not something terribly bad ;)

Appreciate the time you took to answer this.

 

As a matter of fact the two events happened in the last 15 days or so.

This is why I was concerned, sorry I forgot to mention it before.

 

I'll clean all contacts again anyway.

 

I'll see what happens and report back here.

Perhaps it is unrelated, but I have had the same issue with my XTI when my battery power is on the low side. In fact, it has happened to me several times in a row, but as soon as I replace the battery with a different one, all is well.
